Achieving a Simplified, Multi-omics Workflow

An article by Yuchen He et. al. titled “Multi-omic Single-Shot Technology for Integrated Proteome and Lipidome Analysis” was recently published as one of the cover stories in Analytical Chemistry.

This article describes a technology to achieve broad and deep coverage of multiple molecular classes simultaneously through Multi-omics (proteome, lipidome, and metabolome) single-shot technology (MOST), requiring only one column, one LC-MS instrument, and a simplified workflow.

Adding FAIMS to the phosphoproteomic workflow

Mass spectrometry is the premier tool for identifying and quantifying protein phosphorylation on a global scale. Analysis of phosphopeptides requires enrichment, and even after the samples remain highly complex and exhibit a broad dynamic range of abundance. A recent publication by Muehlbauer et. al. found that incorporating a commercialized aerodynamic high-field asymmetric waveform ion mobility spectrometry (FAIMS) device into the phosphoproteomic workflow was a valuable addition with greater benefits emerging from longer analyses and higher amounts of material.
